未来网络的关键问题之一是如何在异构和快速变化的环境中有效地传输由各种应用产生的数据流量。从互联网历史中吸取的教训是，由TCP执行的拥塞控制可以是一种解决方案。然而，由于TCP版本的限制，应用基于喷泉码的传输的新范例似乎是一个有前途的替代方案。在本文中，我们解决这个问题，通过调查我们最近开发的传输协议称为数字喷泉通信协议（DFCP）。DFCP的运行在三个不同的测试平台上进行了验证，包括我们的实验室测试平台，Emulab网络仿真环境和ns-2网络模拟器。我们提出并讨论了一个全面的性能评估研究的结果，通过比较DFCP广泛使用的TCP版本，以及使用各种网络拓扑结构和设置在多个平台上。结果表明，基于数字喷泉的传输方式比传统的TCP传输方式有许多优点.
One of the key questions for future networks is how to efficiently transfer data traffic generated by versatile applications in heterogeneous and fast changing environments. The lesson learned from the history of the Internet is that congestion control performed by TCP can be a solution. However, due to the limitations of TCP versions a novel paradigm applying fountain code based transfer seems to be a promising alternative. In this paper we address this idea by investigating our recently developed transport protocol called Digital Fountain based Communication Protocol (DFCP). The operation of DFCP is validated on three different testing platforms including our laboratory testbed, the Emulab network emulation environment and the ns-2 network simulator. We present and discuss the results of a comprehensive performance evaluation study obtained on multiple platforms by comparing DFCP to widely used TCP versions, as well as using various network topologies and settings. The results point out that digital fountain based transport has many advantages over traditional TCP.
